ABS — the Automated Ball-Strike System

5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Iván Herrera — ump said strike, robot ruled ball: overturned.
  2. 2Iván Herrera — ump said strike, robot ruled ball: overturned.
  3. 3JJ Wetherholt — ump said ball, robot ruled strike: overturned.
  4. 4Jordan Walker — ump said strike, robot ruled strike: upheld.
  5. 5Iván Herrera — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
